The 22-year-old singer - who has previously dated John Mayer, Jake Gyllenhaal and Joe Jonas - insists her mind is constantly filled with thoughts of both "faith and disbelief" about romance and she worries true love will not be part of her future. She said: "I think that one thing I`m really afraid of is ... that magic doesn`t last. That butterflies and daydreams and love, all these things that I hold so dear, are going to leave some day. "I haven`t had a relationship that`s lasted forever. I only know about them starting and ending. Those are my fears. I spend a lot of time balancing between faith and disbelief." Despite the `We Are Never Ever Getting Back Together` hitmaker`s concerns, Taylor isn`t worried about "looking youthful forever" but she is keen to have a young person`s mentality for as long as she can get away with it. She explained: "I think there`s something we have as little kids that goes away sometimes. I don`t care about looking youthful forever, but I care about seeming youthful." While the blonde beauty is known for pouring her heart out in her song lyrics, which are largely based on her real-life experiences, she is thankful for having a "crazy imagination" during her childhood. She added in an interview with The Guardian newspaper: "A fairytale is an interesting concept. There`s `happily ever after` at the end, but that`s not a part of our world. Everything is an ongoing storyline and you`re always battling the complexities of life. But what I got from fairytales, growing up, was a beautiful daydream. I`m glad I had the craziest imagination and believed in all sorts of things that don`t exist."
